Chemical risk is a function of hazard and exposure. In the past, risk management focused on strategies to reduce the exposure after it occurred. Incorporating green chemistry principles into risk management reduces the hazard before it occurs. Renewable feedstocks and alternative reaction media can be used to produce products with an

Formation reactions and their enthalpies are important because these are the thermochemical data that are tabulated for any chemical reaction. Table 7.2 “Enthalpies of Formation for Various Substances” lists some enthalpies of formation for a variety of substances; in some cases, however, phases can be important (e.g., for H 2 O).
